Powering down, powering off

Plug load energy—from computers to copiers to water coolers—represents a relatively untapped energy savings resource in commercial buildings. And unlike most types of loads like lighting, heating, and other end uses, plug load energy use is increasing nationwide. The energy efficiency industry needs to do more to both identify and quantify strategies for reducing plug load.

Tested strategies for reducing office plug load

Seventhwave, along with the Center for Energy and Environment and LHB, conducted a field research study to demonstrate and measure savings from potential plug load reduction strategies in office buildings. We also characterized the types of devices and baseline usage in those offices, and documented occupant acceptance, operational issues and the cost-effectiveness of reduction strategies.
